Lance Armstrong is back on the bike.
Three days after surgery to fix his broken right collarbone, Armstrong posted a photo of himself training on his Twitter feed Saturday afternoon.
"Got on the spin bike for half an hour today," the seven-time Tour de France champion wrote.
The 37-year-old American cyclist was expected to resume training almost immediately to meet his goal of racing in the Giro d'Italia, which begins May 9.
He also plans to ride in the Tour this July, his first since 2005.
Surgeon Doug Elenz inserted a stainless steel plate and 12 screws to stabilize the broken collarbone Wednesday, two days after Armstrong crashed in the first stage of the Vuelta of Castilla and Leon race in northern Spain.
